\(\frac{x-5}{3}=\frac{6}{5}\)
\(x-5=\frac{6}{5}.3\)
\(x-5=\frac{18}{5}\)
\(x=\frac{18}{5}+5\)
\(\Rightarrow x=\frac{43}{5}\)
Vậy ...
\(\frac{1}{3}=\frac{2-x}{4}\)
\(\frac{4}{3}=2-x\)
\(x=2-\frac{4}{3}\)
\(\Rightarrow x=\frac{2}{3}\)
Vậy ...
x - 5 = 6 * 3 / 5 => x - 5 = 3.6 => x = 8.6
2 - x = 4 / 3 => x = 2 / 3
a) \(\frac{x-5}{3}=\frac{6}{5}\)
5 . ( x - 5 ) = 6 . 3
5x - 25 = 18
5x = 18 + 25
5x = 43
x = 43 : 5
x = 8,6
a) \(\frac{1}{3}=\frac{2-x}{4}\)
4 = 6 - 3x
6 - 4 = 3x
2 = 3x
x = 2 : 3
x= \(\frac{2}{3}\)
Theo đầu bài ta có (quy đồng)
5(x-5)=18
5x-25=18
x=43/5
b
Theo đầu bài ta có
4=3(2-x)
4=6-3x
2=3x
x=2/3
